Exposure to the sun’s ultraviolet rays can cause freckles and wrinkles, of course, but in more serious cases, sun exposure can lead to skin cancer.
Skin cancer accounts for nearly half of all cancers in the United States, making it the most common type of cancer. Most skin cancers are non-melanomas, which include basal cell and squamous cell skin cancers. Non-melanomas often occur on sun-exposed areas of the body, including the face, neck, and ears. These cancers rarely spread to other parts of the body. In contrast, melanoma is a more serious form of skin cancer that can spread to other body parts in its more advanced stages. It develops in melanocytes—cells that produce the melanin, or pigment, of the skin. While melanoma is much less common than non-melanoma types of skin cancers, it accounts for most skin cancer deaths.
“Overexposure to sunlight is a major preventable risk factor for all types of skin cancer,”
“There’s no reason why you can’t enjoy the outdoors, but it is important to exercise common sense when it comes to sun exposure and your health.”
Having regular skin screenings by your primary care doctor or dermatologist is also recommended as early detection of cancer leads to better treatment outcomes.
During Skin Cancer Detection and Prevention Month this May, it is a good time to remember these important tips for protecting your skin from the sun:
- Use a sunscreen with an SPF of at least 30 (and remember to reapply after swimming or perspiring).
- Limit sun exposure between the hours of 10 a.m. and 4 p.m.; find some shade if you are out in the middle of the day.
- Wear sunglasses with 99-100 percent UV absorption to protect your eyes and the surrounding skin.
- Wear a wide-brimmed hat to help protect your face, ears, and neck. If you’re wearing a baseball cap, remember to apply sunscreen to your ears and neck.
- Wear protective clothing. Clothes made of tightly woven fabrics work well. Do a check by holding a garment up to the light. If you can’t see through the fabric, it’s a good choice.
- Avoid other sources of UV light, such as tanning beds and sun lamps.
